Like a few other members on this forum, I've had issue with pulsing brakes. Coming to a stop smoothly was difficult due to an on/off sensation under constant light braking. Under firm braking, there was little to no pulsation. My rotors looked fine with no obvious run-out, and the issue seemed to be getting worse over time. This is a brief note on what I tried, and what eventually solved the problem.
1) Cleaning discs with brake cleaner - no change
2) Lubricating the floating rotor contact points ("brake buttons") - no change
3) De-glazing the rotors with scotch-brite pads and brake cleaner - some benefit, still not happy with results
4) Replacing the stock front brake pads with EBC HH pads - 100% resolution of issue, perfect brakes now
I was really concerned that I was going to have to change the front discs to eliminate my issues ($$$), but ultimately a quick pad change was all it took. I'm fairly certain that the stock pads left an uneven deposition of material on the discs that I couldn't fully remove with a de-glazing procedure. The aggressive compound on the EBC HH pads scrubbed this off immediately and left me with smooth braking. Very happy with the results, and wish I had done this sooner!
